lol I still don't have a way that always works.
Alot of times guitar helps me, although because of the music I play (rock/metal) sometimes I go with playing keyboard instead; it takes less effort and I can sit down if I want. I recently got an acoustic guitar for my birthday and noticed its possibly more effective than keyboard with the same or less effort needed. Really any form of art. Drawing and writing too. Just using things as outlets for it temporarily helps with motivation to do other things.
